Specification of Letters Patent.

Application filed March 25,1919. Serial No. 285,060. I

ported and carried by a metallic frame-' work; and my improvements are directed to certain novel features in the framework whereby itis made readily adaptable for use under varying conditions, and whereby, also, the strength and durability of a completed wall are increased, particularly as is pointed out in the specification and illustrated in the accompanying drawings, wherein,Figure 1 is-an elevation of a section of my improved metal skeleton framework,

. supporting plaster boards, and being short- I ened by the breaking out of a portion of its upper area; Fig. 2, is a horizontal section on an enlarged scale, of a completed wall, taken .on a line corresponding to 2'2 of Fig. 1 and looking down; Fig. 3 is a vertical section, also on an enlarged scale, of a completed wall taken at right angles to Fig. 2, as though on'the line 33 '0f Fig. 1; Fig. 4 is a side view, on a still more enlarged scale, of a. section of a skeletonized metal stud; Fig. 5 .is an endlvlew of the same; Fig. 6 is'i-fa; side view of a modified stud; Fig. 7 is an 'end view of. thesame; Fig. 8 is a view, in perspective, of an adjustable anchor adapted to cooperate with the studs; Fig. is "a side view of a section of the cap or top member of a partition suspended from a girder by my improved anchors; Fig. 10 is a similar view showing a modified form of; anchor, and also showing the ceiling plaster board and finish; Fig. 11 is a view of the same taken at right angles to. Fig. 10 and looking to the left; Fig. 12 is a vertical section of a wall to which my improved skeleton framework is attached by means of my imp'roved anchors, the view being shortened by omitting a medial portion andthe plaster being left out of the upper portion; Fig. 13 is a horizontal, sectional view taken on the line 1313 of Fig.

l2, looking down; Fig. 14 is a horizontal section of two, walls spaced by the use of anchors embodying my improved. construction; Fig. 15 is a horizontal section showing the use of one form of my improved anchors" to support molding boards upon the studcling to receive concrete to form the body of the wall; Fig. 16 is a vertical section of the same, omitting the concrete; Figs. 1.7, 18, 19, 20 and 21 illustrate modifications of Patented May 4, 1920.

my improved anchor; F 22 is an eleva tion and Fig. 23 is a horizontal section of a section of studding attached to'a wall by a strip anchor; Fig. 24 is an edge elevation, I

and ig. 25 is a horizontal section illustrating a method of splicing the studding; Fig. I

26 is a side elevation of a section of studding to which-is applied an auxiliary corner member; Fig. 27 is an end view of the corner member; Fig. 28 is a horizontal section of a plastered corner in which the metal corner member is supported by the studding and embedded; Fig. 29 is a cross sectioned view and Fig. 30 is a vertical sectional view on the line 30--30 of Fig. 29 illustrating another method of splicing the studding.

Similar parts are designated by similar ref erence numerals in all the figures. The studding 1 is preferably composed of two parallel and preferably similar members 2, 2, which are secured to each other, preferably by spot welding, as indicated in Fig. 30, although rivets or other suitable securing means -may be employed if desired. These members 2, 2 are provided with vertical grooves 3 3 to receive the plaster board panels 4, 4,'or the concrete or cement if such panels are not used. Their edges are bent inward toward each other, at an angle of about forty-five degrees, and are pierced by holes or perforations 5, 5 suitable to afi'ord a secure anchorage for the plaster, without unduly weakening the studding, and also to serve the other purposeshereinafter pointed out.

The edges of the members 2, 2 are separated, as shown, and this arrangement gives an opportunity for the plaster to enter between them, in the construction of the wall; and to substantially fill allthe space between these members 2, 2, so that they are thoroughly embedded in the plaster. The studdin ceilin y bolting it, as shown in Figs. 1 and 3, wit bolts 6, 6, to channel bars 7 7 which are secured to the floor and ceiling by any suitable means, as, for instance, the bolts 8, 8. The studding ma be adjusted to the desired lengths either y cutting it ofi, if

too long, or by splicing it, if short, for instance, as shown in Figs. 24 and 25, by overlapping the opposed members and then Clamping them together by strap iron clamps, 9, 9, passed through the openings 5, 5, and then bent over as shown; or by butting two sections and placing stiffening plates, as 1O, 10, between them, as shown in igs. 29 and 30. In Fig. 30 the numerals 31, 31 indicate the spot-welds on the sec-' tional view. If, because of the length of the studding or other conditions, it is desirable to increase its rigidity, it may be assembled with a stiffening plate 11, held between its members as indicated in Figs. 6 and 7.

In the construction shown in Figs. 1, 2,

and 3 I have illustrated how plaster boards 4, 4 may be held in placebetween the stud- When this foundation has been prepared for the wall, the plaster 14 may beapplied, and the wall finished in the usual manner.

In erecting structures of this general construction, it is desirableto provide, simple and effective means for a'ttaching the studding elements both'laterally and horizontally and to each other, and the form of the studding, which presents an undercut groove on each side,'can be taken advantage of so as to afford a suitable hold for an anchor, as 15, which is provided with a dovetailed end 16 which may be turned on edge and inserted between the edges of the sides 2, 2, and, when adjusted transversely of the groove, cannot be withdrawn. This end 16 may be of the simple dovetailed form shown 1n ig. 8, or, where it is to be used with the reinforced studding shown in Figs. 6 and 7, the dovetail may be slotted as. at 17, Fig. 18, or halved as at 18, Fig. 19, or curved as at Figs. 20 and 21, so as to permit of its being inserted in the undercut groove past or around the plate 11.

The other end of the anchor 15, may be turned over at right angles as at 19, Fig. 8, or bifurcated, and half turned in each direction as at 20, Fig. 17; or the anchor may be formed double with elongated ends adapted to be .bent over tb grasp a beam or other anchorage, as in Fig. 10; or the anchor may be formed flat with a dovetail at each end, as in Fig. 14. These various modifications adapt it for use under different conditions, as will be explained. These anchors may be. used when it is desired to secure something to the studding, as, for instance, form boards for concrete as illustrated in Figs. 15 and 16. In these fi ures the use of the bifurcated anchor of ig. 17 is shown to hold Jthe'upper edge of one board 21 and the lower edge of the next board 22, at the same I time, by its flanges 20, 20. The form of Fig. 8 might be used by using two anchors together, one with the flange 19 turned up, andthe other with that flange turned down, to hold the two. boards in a. similar way. When the concrete has set, ,the anchors can be broken off, if ,they cannot readily be withdrawn, and the marks left by the anchor will be covered by the finishing coat.

At Figs. 12 and 13 I have shown a form of anchor in which the end 19 has lateral extensions 23, 23, which are pierced to receive fastenings, as nails 24, 24, whereby it may be secured to a wall or backing so as to hold. the partition away from the wall and leave an air space between them.

At Fig. 14 I have shown the use of a modified form of anchor to space two walls with an air space between them. In Figs. 9, 10 and 11, I have shown the use of the anchors for supporting the ceiling to overhead girders. In Fig. 9 the anchors are of substantially the form. shown in Fig. 8; and in Figs. 10 and 11 two anchor elements are united, as by spot welding their-dovetailed ends 16, 16 together. Theiropposite ends are much elongated, and in their initial positions extend right and left at right angles to the ends 16, 16. These long ends 29, 29 may be bent over so as to clamp upon an overhead support, such as the bottom flange of an I beam 28,- and firmly attach the anchor thereto. The head of the anchor being entered within the undercut groove between the sides 2 of the studding or stringer 1 carries the same and the composite ceiling formed in combination therewith in a way similar to the formation of one side of the wall shown in Figs. 1, 2 and 3.

For ceiling and some other classes of work it may be preferable to shorten the lower arms of the members 2, 2, as shown in Figs. 11 and 23 so that less plaster shall be required to cover them, and the construction may be lighter in consequence.;.-'

At Figs. 22 and 23 I have shown the studding as attached to a wall by a metal strip passed through the holes 5, 5, and nailed to the wall. In this case it serves as a furring strip, providing an air space between the main wall and the plaster finish. And this arrangement is peculiarly desirable Where fire proof finish is desired set'off from the main walls.

Where, in erecting partitions embodying my improvements, exterior angles are formed, it is desirable to reinforce the plaster of these angles with a metal element adapted to prevent the corner from being lid easily chipped or broken away. In Figs. 26, 27 and 28 I have shown the use of an improved corner member, 27, which is formed of sheet metal folded. upon itself with its edges bent to form hooked flanges adapted to gras one of the flanges {of a member 2 of the studding 1. The flange 26 is arranged to hook over the free edge of a studding flange while the'fiange 25, is proportioned to be sprung over the angle of the member 2, the flange having sufiicient elasticity to slip over the angle of the stuldding and then snap into place behind it./ This arrangement allows the corner member 27 to be applied laterally to the studding, after the latter has been erected in place, in a simple metal W rkers.

and expeditious manner and so as to be securely attached to the studding; If greater security is desired, a metal strip or wire might be passed through a hole 5 in the corner member 27 and around or through the holes of the studding 1.

It will be seen from the foregoing that theprinciples embodied in my novel construction are susceptible of various minor modifications in applying them to use, without departing from the spirit of my invention, or losing the'advantages of compactness, ease of erection and attachment, and suitability for application under varying conditions, some of which I have pointed out above. The metal elements, may be shipped in a knocked down condition and may be readily fitted and erected by ordinary mechanics, who need not be skilled This increases the desirability of y improved structural materials, broadens the field for their use, and aids in the wider adaptation of the improved methods of construction which they embody.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is 1, In building construction, the combination of, skeletonized metal studding, top. and bottom channel bars, a system of intermediate, vertical channel bars having inwardly deflected, separated edges forming between them, longitudinal undercut grooves constituting anchor seats, a system of intermedi- -erally disposed,

ate horizontal. channel bars, and incombustible panels supported thereby.

'2. In building construction, the combination of skeletonized metal studding units provided with inwardly deflected, separated edges forming undercut grooves therein and also provided. with panel receiving grooves,

of detachable and adjustable anchors protom of intermediate horizontal channel bars,
